SIDE SENSING FOR ELECTRONIC DEVICES

摘要

Side sensing for electronic devices. An input device has a first sensing region including a first plurality of sensor electrodes configured to sense objects in the first sensing region that are ohmically coupled to the first plurality of sensor electrodes. A second sensing region is positioned adjacent to the first sensing region and includes a second plurality of sensor electrodes configured to sense objects in the second sensing region that are ohmically isolated from a second plurality of sensor electrodes but are capacitively coupled to the second plurality of sensor electrodes.
